My experience with previous mini vans is that the top of the rear bumper is especially exposed to wear-and-tear. Mainly from loading things in and out of the cargo area. I know KIA has a rear bumper film that's supposed to add protection. Does anyone have this on their Carnival? Or any other aftermarket protection? And I'm not talking about the rear bumper protection that hangs down to protect from careless parallel parkers. This is specifically for the top of the rear bumper, much like many SUV's. Thank you!
